Abstract: ABSTRACT       A serially interconnected chain of reclosable, zipperlock plastic bags is arranged for facilitated handling in an automatic bag filling machine.  The bag chain may be formed with single or plural connecting spot links between side edges of adjacent bags to maintain alignment of the bags in the chain as the chain is unwound from storage and threaded along a lateral transport path running through the filling machine.  The connecting links are adapted to be broken during the loading operation so that separate, loaded bags may be discharged from the machine for packaging.  Each bag is formed with raised ridge surface means running laterally thereacross adapted to be slidably received in a suitable guide track means of the filling machine to provide vertical support for the bags as the chain is being drawn between various work stations in the filling machine.

Abstract: METHOD AND APPARATUS FOR USE IN COATING AN ELONGATE FILAMENT    Abstract of the Disclosure To uniformly coat a fiber, it is fed downwards through a passage filled with a coating fluid.  The passage has a downwardly tapering lower zone into which fluid is directed from outside the passage uniformly, radially inwardly and downwardly.  The fluid directed into the lower zone suppresses turbulence within the fluid at a bottom outlet aperture within the lower zone.  The passage at an upper zone is large enough to allow bubbles to float to the surface of the fluid.  The arrangement prevents turbulence and air bubbles from causing thinly coated fiber regions which might adversely affect the fiber integrity.  The passage is defined by two relatively moveable bodies so that the rate at which the coating fluid is injected into the lower zone can be varied.                             - i -

Abstract: VOLTAGE CONTROLLED, INVERTER-MOTOR SYSTEM     ABSTRACT      A relatively simple inverter-motor system, compris-ing a minimum number of circuit components, is provided by  employing  a  voltage-controlled  thyristor inverter (65,111) which in turn drives a synchronous motor (81) having a leading power factor.  With the motor current leading the motor voltage,  the thyristor switching devices  (71-76,114-119)  will  be  motor-commutated, thereby precluding the need for any auxiliary commutat-ing elements or circuits to effect forced commutation. Since, with a leading power factor, the current through a conducting thyristor falls to zero before the thyris-tor has to be switched off, ample turn-off time is provided.  Furthermore,  as  compared  to  a  conventional forced commutated voltage source inverter, the customary reactive diodes, usually shunting the switching devices in an inverter to permit the flow of reactive motor current, are not necessary.   Moreover, by powering the inverter with a voltage source  (51,62,63,110),  rather than with a current source, the commutation process is greatly facilitated, the need for damper windings on the motor is eliminated, and the physical size of the d-c link inductor normally required by a current source inverter is greatly reduced.

Abstract: ABSTRACT OF THE DISCLOSURE    Amorphous and polycrystalline films of KP15 are formed by RF diode sputtering targets of KP15 and excess phosphorus in an arson phase.  Substrate temperatures up to 280-300°C provide amorphous films.  Higher temperatures provide micro-crystalline or polycrystalline films.  These films have high resistance and may be used as the insulator in MIS devices employing III-V semiconductors.  Co-sputtering with nickel increases the conductivity of the films from approximately 10-10(ohm-cm)-1 to 10-2(ohm-cm)-1; only reduces the optical gap by 0.2 eV; and reduces the activation energy from 0.8 eV to 0.2 eV;  the nickel content varying  from  5-15%.   Sub-strates include glass, silicon, tantalum, stainless steel, gallium phosphide and gallium arsenide, and glass metallized with metals such as titanium, nickel and aluminum.  Double diode electrical characteristics have been observed in de-vices  formed  on  metallized  glass  substrates  having  co-sputtered thereon thin film polyphosphides and nickel with nickel and titanium top contacts.

Abstract: LONG RELEASE COIL HAMMER ACTUATING MECHANISM             Abstract of the Disclosure An actuating mechanism comprising a magnetic circuit formed by a permanent magnet (43), a flux plate (45), a return plate (47), a post (49), and a long release coil (51) is disclosed. The flux and return plates (45 and 47) lie in parallel planes located on opposite sides (poles) of the permanent magnet (43) and extend outwardly therefrom in the same direction. The post (49) is mounted on the end of the flux plate (45) and the release coil (51) is mounted on the post. The outer end of the release coil (51) terminates slightly short of the tip of the post. Further, the post (49), long coil (51), flux plate (45) and return plate (47) are sized and positioned such that the tip of the post (49) lies coplanar with the outer surface of the return plate (47) and such that the end of the return plate(47) terminates just short of the release coil (51). The fixed end of a cantilever-mounted hammer (53) is attached to the outer surface of the return plate in (47)alignment with the permanent magnet (43). The head (59) of the hammer (53) is positioned to be attracted to the post tip and the adjacent area of the return plate (47) by the magnetic flux created by the permanent magnet (43) when the long release coil (51) is not energized. The permanent magnet attraction force bends the head (59) of the hammer (53) across the small gap resulting in the hammer (53) being stressed, i.e., cocked. When the long release coil (51) is energized, it produces a magnetic field that counteracts the permanent magnet attraction force, releasing the cocked hammer. Release of the cocked hammer impacts a ball (61), welded to the side of the hammer (53) remote from the pole tip, against a ribbon to create a dot on a print-receiving medium. Because the release coil (51) terminates just short of the tip of the post (49), the intensity of the flux produced by the coil (51) at the interface between the post tip and thehammerhead (59) is high. As a result, for the same amount of applied coil current, the amount of drag force created by the permanent magnet (43) after the hammer (53) is released is lower than it would be if the release coil (51) were spaced a substantially greater distance from the tip of the post (49).
